The improved varieties are becoming more important for sugarcane production worldwide [6, 7]. New varieties are continuously released in Guangxi, Guangdong, Yunnan, Fujian, and Hainan by sugarcane breeding institutes, agricultural universities, and sugarcane research and development centers in China (**Table 1**). It would be therefore worthwhile for the growers to manipulate the environment in such a way as to bring out the maximum expression of the yield potential possessed by these varieties.
